apple tv and harman kardon receiver?

I just bought a new harman-kardon avr 247 receiver

Problem is that when I hook up the apple tv to the hk via component video, it will only display the apple tv while rebooting? Have the avr going to my tv via hdmi which does work fine with my directv component setup?

I also down sized the output from apple tv to 480i all the way to 1080i with same issue.

Any suggestions?


Thanks
